Nginx User Guide

Nginx User Guide

1. Run nginx

You can run the nginx command to enable nginx:

nginx

If nginx is enabled, run the nginx command and add the-s parameter to control nginx running.

nginx -s signal

Signal Value:
Stop-Quick Close
Quit-elegant close
Reload-reload the configuration file reopen-re-open the log file

For example, you can use the following command to disable nginx after nginx finishes processing the current request.

nginx -s quit

After modifying the configuration file, run the following command:

nginx -s reload

2. Configure nginx

Open the configuration file, usually in/etc/nginx. cnf, depending on your own installation parameters.

Nginx. conf already contains a server block configuration case, but it is commented out. Below is the basic configuration of a server Block

http {    server {    }}

Server block, you can configure some locations to specify the local resources corresponding to the request url.

location / {    root /data/www;}

The above indicates that all access resources under/are under the/data/www folder.

location /images/ {    root /data;}

This indicates that all images accessed by the/images/path are under/data.

The preceding unified configuration is

server {    

listen 8080; 

Location/{root/data/www;} location/images/{root/data ;}}

If I access http: // localhost/images/example.png, nginx will return the example.png image under/data/images/in the file directory to the client.

If I access http: // localhost/some/example.html, nginx will return the example.html image under/data/www/in the file directory to the client.

Listen can be left unspecified. The default value is 8080.

If the configuration is modified during running

nginx -s reload

If the configuration is verified, but the specified file is not accessed as agreed, you can view the log file access under/usr/local/nginx/logs or/var/log/nginx. log and error. log

3. Configure reverse proxy

server {    location / {        proxy_pass http://localhost:8080;    }    location /images/ {        root /data;    }}

Proxy_pass specifies the reverse proxy path. All the paths that match the/will go to http: // localhost: 8080 to obtain resources.

For example, the resources accessed by http: // 192.168.1.100/some/example.html are actually resources obtained by http: // localhost/some/example.html, which are transparent to the client.
